Engine And Engine Cooling Problems of Toyota Tundra - part 2

Manufacturer recall number25tb06 NHTSA recall number25v322 in regards to the above mentioned recalls. The vehicle's reverse camera began flashing while driving forward. The r light on the gearshift was also flashing. While driving forward about 15 mph out of a parking lot, the vehicle suddenly went into reverse on it's own, locked up and would not move. I had to have the vehicle towed to the dealership. This happened around the week of June 8. The dealership says that they reset the electrical recall, we picked up the truck and it ran fine for about a week. The reverse camera and r light on the gearshift began flashing again on June 17. It did not shift itself into reverse, but the dealership requested that we bring the vehicle back. The dealership stated that Toyota has "grounded" the vehicle and does not have a fix for the recall to date and continuing to drive it is a safety hazzard. It has been sitting at the dealership since June 18 with no end in sight. The dealership and Toyota corporate continues to tell me every few days that they do not have a fix for the issues/recalls.

While traveling on us highway 95 between lewiston and riggins, idaho, a 2024 Toyota Tundra trd pro with approximately 18,000 miles experienced a sudden loss of engine power while descending a mountain grade with multiple curves. The driver reported hearing abnormal engine noises immediately before the loss of power. At the same time, the brake pedal became extremely hard to depress and the vehicle did not decelerate as expected, requiring substantially increased braking effort. The vehicle was carrying family members and was traveling on a winding downhill section of highway adjacent to steep terrain. Due to the loss of power and increased braking effort, the occupants feared the vehicle would be unable to stop safely. Fortunately, a roadside pullout area was available, and the driver was able to steer the vehicle into the pullout and bring it to a stop without a collision. The vehicle was towed to an authorized Toyota dealership for inspection. The dealership diagnosed the vehicle with a catastrophic engine failure requiring engine replacement. The failed engine remains in the possession of the dealership and should be available for inspection. Approximately five days before this incident, the vehicle had undergone routine maintenance, including an oil change and inspection at a Toyota dealership. The vehicle had also previously been presented for brake pulsation concerns and other drivability-related complaints. The vehicle was returned to service and represented as operating normally. No collision occurred and no physical injuries were reported; however, the incident created a significant safety risk because the loss of engine power occurred while descending a mountain highway and the driver experienced substantially increased braking effort while attempting to stop the vehicle.

The engine lost power and shut down at highway speeds which put myself and a passenger at risk for a crash. There were no warning lights or other symptoms before the engine shut down. After pulling the vehicle over to the side of the road, I attempted to restart the engine. The engine failed to turn over and start. The truck towed into a local dealership and is waiting inspection.

Have owned the 2025 Toyota Tundra for about 18 months. Multiple instances of delayed acceleration when stopped or almost stopped, sometimes as much as 3 or 4 seconds. Last time was in early June, 2026. This is very dangerous because when I pull out into an intersection it will start to go but then lose all power for a few seconds with traffic coming behind me. This is something Toyota needs to look into.

Three recalls have now been issued across four years post-fix engines are still failing for the new Tundra Toyota is still issuing new part numbers and design revisions for 2026 the NHTSA filing explicitly references engine configuration as a pressure driver no complete remedy exists for the second recall as of today the probability this is purely a manufacturing debris issue is effectively zero at this point. As one insider on bobistheoilguy summarized: "Toyota is not telling the public the entire extent of the issue because all vehicles with that engine are experiencing failures and because it's at least partly a design flaw issue — even the replacement motors will fail. " bobistheoilguy what Toyota has is a design that operates with insufficient margin at #1 main, which means it will continue to surface failures even in "clean" engines under the right combination of load, heat, and mileage — just at a lower rate than the heavily contaminated early production units. That's why there's no clean fix. You can't recall your way out of a physics problem. This is a engine defect. Toyota needs to buy back all these vehicles.

Engine shutdown while driving (was towing a travel trailer at the time) and after coasting to a stop the engine would not start. After 10 minutes the engine would start, but had loud knocking. My 2024 Tundra only had 31,726 miles and had to be towed to the dealership. Seems to be the known engine issues with the redesigned v6 engine. Tundra has been in the dealership for 4 weeks and was told it will require engine replacement, but do not know when the new engine will be shipped. While Toyota will perform the replacement free of charge, based on the hundreds of thousands of Tundra's being recalled for this very issue, I no longer trust this engine design (replaced or not).

I have a 2024 hybrid Toyota Tundra equipped with v35-a- fts 3. 4 l twin- turbo v6. This motor is the same engine as the non hybrid motors included in the recall. There was recently a defect information report sent out on may 20th 2026 from Toyota stating that there is an issue with the main #1 bearing and the newer motors are now being installed with upgraded new bearing indicating that all motors, hybrid or non hybrid prior to August of 2024 have this defect that could cause engine failure. The only reason this motor is not included in recall is Toyota saying that it not a safety issue because of the electrical motor is sufficient to get it off the road. I tow a boat and various trailers and feel like at highway speeds in traffic a failure of the main engine, with very limited assistance from electrical motor could cause a potential serious crash leading to serious injury or death. I am filing this to ask NHTSA to do the right thing and have Toyota to expand the recall and include the hybrids as it will only be a matter of time before before something will happen.

2024 Toyota Tundra experienced a serious safety event. While travelling on the highway at 60mph speeds in traffic when the truck suddenly blinked a loss of steering warning light then immediately blinked engine failure warning light. The truck lost power and the engine completely shut down in traffic going down a long, steep hill. I was able to reach the bottom and pull over but the truck would not restart. I had to have the truck towed to a Toyota dealership near my home.

When coming to a rolling or quick stop and then attempting to maneuver across traffic, my truck hesitates for about a full second before accelerating. This delay can create a dangerous situation for myself, other drivers, and pedestrians. I believe this is a safety issue that Toyota needs to address promptly.

I am 99% sure my vehicle is compromised via a cybersecurity incident. My emergency brake will sometimes slam for no reason, no multi media system updates have occurred for over two years, and the vehicle will randomly beep on its own, unlocking the doors. Another major issue is a recent electric harness failure that the mechanics have no idea how it happened. It cost me over 8,000. Warning lights also turn on for no apparent reason such as parking, sensors, and other traction control. I am extremely concerned with my safety. I also believe the odometer has been altered to register higher mileage.

I've been experiencing throttle lag on my 2022 Tundra in certain situations during rolling stops (I've also had it occur from a dead stop, though more frequent in rolling stops). Sometimes there is a significant delay in throttle response, and the other day while pulling out into traffic the delay was perhaps 2-3 seconds. This nearly created an accident as the engine had zero response and greatly affected my ability to accelerate quickly enough. Please consider this as a possible recall, as the danger level is very high for this known issue. Thank you for your time.

The contact owns a 2025 Toyota Tundra. The contact stated that the vehicle was leaking oil. There was no warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed that the gasket needed to be replaced. The vehicle was not repaired. The contact requested a buyback. The manufacturer was not notified of the failure. The failure mileage was approximately 34,000.

I have a 2024 hybrid Toyota Tundra which shares the same engine that has undergone a NHTSA recall. I do not believe that the defect has been satisfactorily addressed to mitigate the risk of catastrophic engine failure in the v6 engine. I would like the recall to include the hybrid models as well for this well known and documented engine failure risk. I have not yet had any problems with the engine yet and am addressing the other separate recalls for this model. From a safety and liability perspective, I feel that Toyota has an obligation to provide the same warranty extension assurance and if needed, engine replacement as the gasoline only variant.

I was driving on the freeway in my Toyota Tundra when it suddenly shut off completely. It was honestly terrifying because my first thought was getting rear-ended in traffic. After about 15 seconds, the truck randomly turned back on by itself, but the whole situation really shook me up. A vehicle that new shouldn’t be doing something that dangerous.

The contact owns a 2024 Toyota Tundra. The contact received notification of NHTSA campaign number: 25v322000 (exterior lighting) and 25v767000 (engine and engine cooling) however, the part to do the recall repair was not yet available. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the issue. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact had not experienced a failure.

I have only owned the truck since mid April of 2026. The truck has 12000 miles on it. I have only put 200 miles on the truck. . . 150 miles are driving to the dealership. Engine recall notification was sent out last week of may 2026. Still an open recall for reverse lights with no remedy. Took Tundra into dealer at the beginning of may 2026 to get two other "electronic/infotainment" system recalls repaired. I bought the truck used from a dealership. Had three open recalls (electronic x's 2 and reverse light). Got two of three fixed. A few weeks later I get the engine recall. Really Toyota. . . I took the truck to maplewood Toyota on 5/28/26. There it sits waiting for repairs. I asked about getting out of the truck and my option was trade it in at kbb value ($45k-ish) I paid $57k and $3k for extended warranty for a total of $60k. I am not going to eat $15k on trading in the truck. Toyota should stop selling vehicles with these engines now! these engines should not be on the road or being sold - period. Toyota still using the "debris" in engine from manufacturing in 2024 is criminal. We are talking about the debris issue in 2022, 2023, 2024 engines. . . . This is outright criminal. Shame on you Toyota. I am a Toyota buyer. I own a 2019 corolla. My friends and family are also Toyota owners. This v35a engine is a complete failure and production should be stopped. I kick myself for not doing more research before buying the truck. I never would have purchased knowing the ongoing engine issues. Dumb me - I am buying a Toyota because I trust there is no reason to worry - boy was I wrong. Please hold Toyota accountable for this. Toyota should buy back every vehicle that has this engine if the owners want that option. Anyone with a 2022 - 2026 v35a engine - drive at your own and everyone else on the road - risk.

I own a 2023 Toyota Tundra that is part of the major engine recall due to machining debris in the 3. 4l v6 engine. A few days prior to the failure, I called the dealership to raise concerns that the acceleration was starting to not act right. Despite this, while driving at 70 mph on the highway yesterday (may 22, 2026), the engine suddenly failed and died without any prior warning, it is my belief that this is due to the open recall. This created a very dangerous situation as I was traveling at highway speed and could have been rear-ended or lost control of the vehicle. The truck had to be towed to the dealership. The truck now has 33,000 miles. I purchased it used for $49,000 with only 11,000 miles. This is the same known defect Toyota has issued a recall for, yet my engine still failed catastrophically. I am extremely concerned that this failure has caused additional damage to the transmission, drivetrain, or other components. I have completely lost confidence in the safety and reliability of this vehicle. Even after the planned engine replacement, I do not feel safe driving it due to the risk of future failure and the known history of this defect. I am requesting that Toyota provide a full buyback or replacement because this sudden engine failure at highway speeds poses a serious safety risk. Toyota has been notified, but I want this incident officially documented with NHTSA due to the widespread nature of these engine failures in 2022-2023 Tundras.

I am filing this complaint regarding an active safety recall on my 2024 Toyota Tundra involving manufacturing debris left in the v35a 3. 4l twin-turbocharged v6 engine during production. This recall has been open for multiple years and spans over 250,000 vehicles across the 2022–2024 Tundra, Lexus lx 600, and 2024 Lexus GX 550. The manufacturing debris causes damage to the engine’s main bearings, resulting in engine knocking, rough running, failure to start, and sudden loss of motive power while driving at speed — a condition Toyota itself acknowledges increases the risk of a crash. Toyota deployed a remedy consisting of full engine replacement; however, Toyota has since acknowledged that the replacement engines are experiencing the same failures, meaning there is currently no confirmed, working fix. Despite this, Toyota continued selling new vehicles with this known defect. Remedy deadlines have been repeatedly promised and repeatedly missed, with the latest expected resolution pushed to July/August 2026 — a deadline that has already slipped multiple times. As an owner, I am left driving a vehicle that Toyota acknowledges is dangerous, with no confirmed timeline for a legitimate repair, and suffering significant financial harm due to the ongoing depreciation and diminished resale value caused directly by this unresolved defect.

Toyota issued a recall (NHTSA 25v322) over a year ago. We are now more than a year beyond the issuance date of this recall and stop sale order for affected vehicles. There is still no remedy available for this recall and from what I can tell, none in sight. Additionally, on 11/6/25, Toyota issued a recall (NHTSA 25v767) related to potential engine failure. Over 6 months after this recall and stop sale notice there is no remedy available. Both of these issues go beyond what most would consider remedying the issues in a “timely manner”.

While driving the vehicle on a public roadway at approximately 70mph, the vehicle suffered a sudden and catastrophic powertrain failure without timely warning. The check engine light illuminated, the physical engine oil pressure gauge dropped to absolute zero, and the dashboard immediately flashed a critical "hybrid system malfunction" warning. > this mechanical and electrical failure triggered an instantaneous, total loss of motor power while traveling live lane with traffic behind me. The vehicle immediately stalled and became a completely inoperable, unresponsive rolling hazard. The vehicle failed to restart and left me stranded on a narrow shoulder which was very hazardous as traffic coming at high speeds could have easily rear ended me. The vehicle required a flatbed tow to an authorized Toyota dealership, and after submitting a case with corporate hoping for a trade assist(as my wife no longer feels safe in this chassis), I have been told it will take up to 45 days to process this request. I made a significant investment in this vehicle in January of 2023 and have since methodically kept up with maintenance, with hopes this vehicle would last me 10+ years. I find it highly inexcusable for Toyota to not consider speedily helping a loyal customer in this situation and making it right in a timely manner. I am now being offered a vehicle the same as mine of the current year and with me having to put over 22k in equity to close the gap. I should not be left on the hook for something that put my safety at risk and now has left me without the ability to travel as my family has lost their main method of transportation. Manufacturing defects should not come at the customers expense.

The issue I’m having is the transmission/engine when it comes to the hesitation for stopping and either slowing down or just a rolling stop. Sometime I would feel like I need to precisely control the brake pedal in order to go smooth stop, but no. It feels like it’s ’jumping’ in Mini burst. I have the hybrid engine of the v35a-fts. I did check for recalls but nothing found but found a TSB from Toyota t-sb-0032-26, but my hybrid is not covered, only the non-hybrid Tundra. Please help. Thanks.

While driving to dinner in bluefield< west virginia on Saturday evening, I came to an intersection where I was making a left hand turn with a green arrow on the light. As I approached the intersection, I slowed to something under 10 miles an hour and proceeded to initiate a left hand turn. As I rolled onto the throttle, there was no response from the engine for approximately 15 seconds. The engine remained at idle as I coasted through the turn. I continued applying throttle with no response until I reached approximately 50% of throttle pedal travel, at which time the engine sputtered then accelerated rapidly. This is not the first instance of this issue. It has happened on at least 4 different occasions in the past. The issue is intermittent and could easily result in an accident if it occurs while pulling out into traffic - which is what happened the first time it happened to me with the oncoming traffic being forced to take evasive action.

I was crossing two lanes of a 4-lane highway from a stop. I floored the accelerator to cross traffic and the truck hesitated for approximately 1-2 seconds in the middle of the highway before finally accelerating. During this time I was completely exposed to oncoming traffic with no ability to move the vehicle. This is not the first time I have experienced throttle hesitation on this vehicle but this was by far the most dangerous instance. The truck has ~17,000 miles and is a 2025 model year.

I was turning left from a stop sign on to a busy road. Immediately after beginning to pull out, the engine stalled and left the truck powerless in the middle of the intersection. I almost got t boned from vehicles traveling both directions. The truck eventually regained power a few seconds after the stall. I had my wife and toddler with me and the situation could have been bad. I no longer the trust the truck which sucks being that it has 2500 miles. Searching online, many owners have had this happen and Toyota refuses to do anything meaningful. This needs to be recall before someone gets hurt, or worse. I’ll be taking the truck in but am doubtful anything will come of it from the dealership.

I was on the highway driving about 70 mph, when the engine suddenly turned off. The lights on the dashboard stated that I needed to pull over immediately. The truck was towed to a dealership who confirmed the engine was "destroyed" due to safety recall 25ta14.

While driving, the vehicle unexpectedly stalled and lost power. The vehicle was taken to an authorized dealership for diagnosis, where the same stalling condition was reproduced and confirmed during a dealer road test. The vehicle had to be towed back to the dealership, where the engine was found to be seized. The sudden loss of power while driving created a serious safety concern because the vehicle could become disabled without warning and lose motive power in traffic. The failure was confirmed by the authorized dealership, and the vehicle and engine were available for inspection during the repair process. There were no known warning lamps, diagnostic messages, or other clear advance warnings that would have allowed me to anticipate the engine failure before the vehicle stalled.

The contact owns a 2023 Toyota Tundra. The contact stated that while accelerating from a stop the vehicle stalled. There was low voltage message displayed. The contact stated that there was metal inside the oil filter. The vehicle was restarted and driven to the residence. The vehicle was taken to the local dealer but was not diagnosed or repaired. The dealer informed the contact that the part to do the recall repair under NHTSA campaign number: 25v767000 (engine and engine cooling) were not yet available. The manufacturer was not contacted. The failure mileage was approximately 14,500.

The contact owns a 2024 Toyota Tundra. The contact stated that while driving at an undisclosed speed, there was an abnormal sound coming from the engine compartment. No warning lights were illuminated. The vehicle was taken to a dealer where it was diagnosed and determined that the short block engine needed to be replaced. The vehicle was repaired. The contact researched and became aware of an unknown recall; however, the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was approximately 20,000.

Stopped at a traffic light, when it changed to green the truck would not move. Displayed hybrid system stopped working, shift into park. We were the first vehicle at the light in a high traffic area with no shoulder. Traffic trying to manouver around our vehicle were at risk of causing an accident. Paramedics arrived to try and direct traffic. The truck had to be towed to the dealership and they verrified that the engine siezed.

I bought the truck brand new in July 2022. May 2, 2026 I hit 46,461 miles and started hearing a clanking sound and caused vibration in low speeds. After 30 mph the vibration went away. I took it straight to Toyota dealer and with hardly any questions asked they are rebuilding the whole engine and still have it since today may 29,2026.

Ubject: urgent safety incident report: engine seizure at highway speeds – case #xxx to the Toyota safety & compliance department: I am writing to formally report a critical safety incident involving my 2024 Toyota Tundra (VIN: [xxx] ). Incident description: while traveling at highway speeds, the vehicle’s engine suffered a catastrophic internal seizure and shut down completely without any prior warning. This resulted in an immediate loss of motive power in the middle of high-speed traffic. Because the engine died, I also experienced an immediate loss of power steering assist and power brake vacuum, making the vehicle extremely difficult to control. I was forced to perform an emergency maneuver to avoid a rear-end collision and struggled to steer the truck toward the shoulder while other vehicles swerved around me at high speeds. Safety hazard & manufacturing defect: this failure is identical to the conditions described in NHTSA safety recall 24v-381 (Toyota recall 25ta14). The dealership's diagnosis at autonation Toyota weston confirmed that the bearings are discolored and "spun," which is a direct consequence of the manufacturing debris that Toyota has already admitted exists in these engine blocks. Bad-faith warranty denial: despite the life-threatening nature of this event, the dealership is attempting to blame "abuse" based on a software log from the brake override system. They are ignoring the fact that a metallurgical failure of the main bearings has no mechanical link to pedal input. Using a safety software record to deny a repair for a known manufacturing defect that nearly caused a fatal accident on the highway is unacceptable. Requested action: I demand that this case be immediately reviewed by Toyota’s safety team. My vehicle manifested the exact defect described in the federal recall during a high-risk situation. I am requesting an immediate resolution to remove this dangerous vehicle from the road and to honor the terms of the information redacted pursuant to the freedom of information act (fo.

The 2023 Toyota Tundra hybrid’s powertrain design may be insufficient to maintain basic safety maneuvers (specifically "limp mode" or emergency clearing) during an engine failure while operating under high-load conditions in mountainous terrain. This creates a life-threatening hazard for the occupants and other motorists. ?statement of fact: as an owner of a 2023 Toyota Tundra hybrid, I primarily utilize this vehicle to tow a 9,000 lbs travel trailer through the high-altitude, steep-grade regions of utah. These routes frequently consist of narrow, two-lane mountain passes with no shoulders and steep drop-offs. ? ?failure under stress: engineering logic suggests that engine stress is highest during heavy towing on steep grades. If a primary engine failure occurs in these conditions, the hybrid system’s battery and electric motor capacity are, in my experience, inadequate to move a combined gross combined vehicle weight (gcvw) of approximately 15,000+ lbs to a safe location. ?while the hybrid system may allow a light, unladen vehicle to limp to a shoulder under "ideal conditions," it lacks the torque and sustained power to move a heavy trailer on a grade once the internal combustion engine is compromised. ?in the event of a failure, the vehicle would likely become "dead in the water" in the middle of a live, narrow lane on a blind mountain curve. Without the ability to reach a turnout or even a marginal shoulder due to the weight of the load, the vehicle becomes a stationary target for other high-speed mountain traffic, posing a severe risk of rear-end collisions and multi-car accidents. ? I am requesting that the NHTSA investigate the performance of the Tundra hybrid’s "fail-safe" modes specifically under maximum towing capacity on grades.

My truck engine seized at highway speeds on 4/29/2026. Machining debris seized to the engine’s bearings causing oil to dump from the engine and the engine to completely seize. This is the same issue that nhsta forced Toyota to issue a recall on 2022-2024 Toyota Tundras.

The contact owns a 2024 Toyota Tundra. The contact received notifications of NHTSA campaign numbers: 25v322000 (exterior lighting) and 25v767000 (engine and engine cooling); however, the parts to do the recall repairs were not yet available. The local dealer was contacted and confirmed that parts were not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure.

While driving, I noticed that the vehicle seemed sluggish. Shortly after, I experienced grinding and knocking. The engine then stalled when I came to a traffic light. Fearing for my safety, I was able to get the engine to re-start to be able to pull off the road into a parking lot. At this point, the engine was barely running and making a ton of noise. There were no warning lights prior or after the incident took place. The vehicle was towed to my local Toyota dealership who performed an inspection and determined that the short block needs to be replaced, despite the contamination risk of other components. I have demanded that Toyota replace the engine with a complete new assembly, however, they are declining to do so.
